For measurements of surface resistivity, ring electrodes are used as described in the standards.

ashm At higher conductivity, where the contact resistance becomes significant, 4-point measurements are done with a Keithley SourceMeter to determine the resistivity in the materials. Add to Alert PDF. In order to measure the conductive properties of materials, different techniques are used depending on resistance: Your Alert Profile lists the documents that will be monitored.

This standard is not included in any packages. Properties lengthwise and crosswise may be different if the composite is filled with fibres or flakes, which have been oriented eg during casting. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. These measurements are carried out in a climatic test cabinet where the temperature and humidity can be varied over a large range, so other conditions are also posible.
